Title: Isomerisation of dichlorobutenes
Inventor: COSTAIN WINSTON
IPC: B01J27/06
Filed: 1963-08-29
Abstract: 1,4 - Dichlorobutene - 2 and 3,4 - dichlorobutene-1 are isomerized separately or in admixture by contacting with a catalyst solution obtainable by dissolving a cuprous halide in a mixture containing a halide solubilizing agent and a water-miscible organic solvent, the catalyst solution being either immiscible with the dichlorobutene or capable of being rendered immiscible with the dichlorobutene by the addition of water or an organic solvent having only sparing solubility in either the dichlorobutene or in the water-miscible organic solvent. The halide solubilizing agent is a halide salt which when dissolved in water is a solvent for cuprous salts.  The water-miscible organic solvent is one which will dissolve at least its own weight of water.  After the isomerization, phase separation is preferably brought about by the addition of water or a sparingly soluble organic solvent as described above.  The separated dichlorobutenes may then be separated into the isomers by distillation.ALSO:A catalyst solution for the isomerisation of dichlorobutenes comprises a cuprous halide, a water-miscible organic solvent which will dissolve at least its own weight of water and a halide salt which, when dissolved in water, is a solvent for cuprous salts. Specified halide salts are NH4Cl, CuCl2, alkali and alkaline earth metal chlorides and halide salts of organic bases. Specified water miscible solvents are hydroxylic solvents such as diols, triols, polyether alcohols and polyols, dialhoxy alcohols, dimethyl sulphoxide and dimethyl formamides.

Abstract: 760,130. Moving bulkheads in vehicle bodies. WALKER & COUNTY CARS, Ltd., VENNING, R. B. H., and TAPP, D. R. F. Dec. 13, 1954 [Dec. 11, 1953], No. 34645/53. Class 78 (4). The transmission for moving a bulkhead 15, Fig. 1, to move material in a compartment comprises one or more endless flexible elements 25 ... 28 guided to form a number of stretches moving simultaneously in the same direction and secured to at least three points on the bulkhead. In the construction of Fig. 1, a pair of chains 25 on each side of a vehicle with telescoping scuppers 10, 11, 12 pass over driven sprockets 18, 20 and are secured at one end to the wall 15 of the inner scupper 10 and at the other end to cables 26, 28 which are returned over pulleys 23, 24 to be secured to the wall 15. The pulleys 18, 20 are fast with pulleys 17, 19 connected by a chain 21 and the common shaft 22 of the lower pulleys is driven from the power take-off of the vehicle engine. The separate endless elements formed by the cables and chains 25, 26 and 27, 28 may be replaced by a single element on each side passed over pulleys and sprockets suitably disposed to form two pairs of runs with those runs moving in the same direction connected to the bulkhead or wall 15. Further the endless elements on opposite sides may be joined to form a single endless element as shown in Fig. 4 in which a cable 30, 32, 33, 36, 45, 51 is passed over suitably disposed pulleys to provide four runs 30, 30, 36, 36 secured to the bulkhead 15 which moves relatively to the inner scupper 10 of a pair of scuppers 10, 11. Any of the pulleys illustrated may be driven or replaced by driving sprockets engaging a portion of chainsecured in the cable. Alternatively, the runs 51 of Fig. 4 may be broken and theirends wrapped around driving drums carried by a common lateral shaft driven from the vehicle engine. In the construction of Fig. 5 two endless elements, each formed of a length of chain 69 passed over sprockets 52, 68 and a length of cable 54, 56, 58 passed over suitably disposed pulleys on the vehicle framework and over pulleys 62, 64 on the inner scupper 10 are secured to the bulkhead 15 at two upper laterally spaced points and to a single central tongue 6 towards its lower end. As indicated in Fig. 6 the pulleys 62, 64 are carried by a bracket 71 which is protected by the inclined wall 70 of the bulkhead 15 from the material in the inner scupper 10. In the construction of Fig. 8 an endless cable 30, 32, 36, 45 reeved as shown is driven by a connection 75 between the run 36 on each side of the vehicle and a run 72 of an endless chain carried by sprockets 73, 74. The sprockets 73 on opposite sides are driven by their common shaft 76 either from the engine of the vehicle or through a manuallyoperated drive from a crank. According to the Provisional Specification chains driving the bulkhead can be driven by a reversible ratchet mechanism driven manually or by power.

IN ACCOMANDITA SEMPLICE DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 10 July, 1969 [11 July, 1968], No. 34905/69. Heading F2Q. In a Geneva mechanism comprising a uniformly rotating drive-wheel 1 carrying eccentrically at least one roller 2 which is drivingly engageable with successive radial slots 4 of a Geneva wheel 3, the drive-wheel 1 having at least one part-cylindrical facial projection 5 coaxial therewith and co-operable with concave surfaces 6 in the Geneva wheel periphery between the radial slots 4 to lock the Geneva wheel between steps, to prevent "kick-back" of the Geneva wheel as the roller 2 leaves a radial slot 4, a concave surface 6 of the Geneva wheel is engaged at this time by a part-cylindrical facial projection 20 on an auxiliary wheel 19 geared to the drive wheel 1. Thus, as the roller 2 leaves a slot 4, forward and backward rotation of the Geneva wheel 3 are prevented respectively by the projection 5 of the drive wheel contacting the trailing part of a surface 6 and the projection 20 of the auxiliary wheel 19 contacting the leading part of a second surface 6. The auxiliary wheel may rotate at the same speed as, but in the opposite sense to, the drive wheel 1, and have the same number of partcylindrical projections as the drive wheel, i.e. equal to the number of rollers 2 (Figs. 11, 17). In Fig. 19, the auxiliary wheel 19a<SP>1</SP> rotates at twice the speed of the drive-wheel 1h<SP>1</SP>, and has only one projection 20a<SP>1</SP>, though the drive-wheel carries two rollers 2h.

Title: Preparation of suspensions of water-soluble solids in oleaginous media
IPC: C09K23/00
Filed: 1958-10-31
Abstract: A method of preparing a suspension of a water-soluble solid in an oily medium is to form a water-in-oil emulsion of the aqueous solution of the solid with oleaginous liquid using a vegetable wax as an emulsifying agent and thereafter dehydrating the emulsion.  The oleaginous liquid may be a mineral oil (e.g. a lubricating oil, a residue, a fuel oil or kerosine), castor oil, a diester, a polyglycol, a polyether or a silicon-containing synthetic oil.  It may be also thickened to form a lubricating grease.  Solids which are suspended in the media include alkali metal and ammonium nitrites, carbonates, bicarbonates, sulphites, borates, chlorates, perchlorates, hypochlorites, silicates, phosphates, salicylates, citrates, tannates, lactates, tartrates, oxalates, phthalates, acetates, iodates, arsenites, chromates, molybdates and tungstates; amine nitrites, phosphates and iodates; hydroxy fatty acids, polycarboxylic acids, hydroxy polycarboxylic acids, sodium benzoate, amides and amino acids.  Waxes specified are carnauba, candelilla esparto, flax and suricury.  In an example, sodium nitrite is dispersed in lubricating oil by the method of the invention, employing carnauba wax as the emulsifying agent, and the dispersion is incorporated in a grease prepared from mineral lubricating oil, lithium hydroxide and hydrogenated castor oil.

It is arranged that, by a defect of balance, the valves V1, V2 interact and sing at a frequency outside the range employed for voice transmission. Filters S1, S2 keep the singing frequency out of the lines L1, L2 and filters S3, S4 prevent it from affecting the echo-suppressors E1, E2.

Abstract: 337,999. Harvie, R. Nov. 18, 1929. Guards for preventing access of vermin.-Foxes and similar vermin are prevented from entering poultry houses by arranging a gangway to communicate at one end with the entrance to the house and fitting in the gangway a rotary turnstile such that fowls may pass therethrough while foxes engage and cause rotation of the turnstile. The gangway 1 is a roofed box-like structure communicating by the doorway 2 with the poultry house. A turnstile 4 comprising a four-bladed structure with arched blades is adjustably pivoted in a series of spaced notches 5 in the side walls of the gangway. The blades are weighted to obstruct the passage of foxes. The turnstile may be removed from operative position by pivoting it in notches 9.
